Abstract

Unplanned excision (UE) of soft tissue sarcoma (STS) often necessitates additional wide excision at referral centers. However, factors influencing local control, residual tumor in re-excision specimens, and the prognostic impact of infiltrative histologies remain unclear. We aimed to evaluate oncologic outcomes after additional wide excision following UE, identify risk factors for local recurrence and residual tumor, and determine whether infiltrative tumors (myxofibrosarcoma [MFS]/undifferentiated pleomorphic sarcoma [UPS]) confer poorer prognosis than non-infiltrative subtypes.
